Converting Decimal Values to Hexadecimal in JavaScript

In JavaScript, converting decimal values to their hexadecimal counterparts is a straightforward task. Here's how to approach it:

To convert a decimal number, yourNumber, to a hexadecimal string, simply use the following syntax:

hexString = yourNumber.toString(16);

This will generate a string representation of the hexadecimal value.

To revert the conversion and obtain a decimal number from its hexadecimal string, use the parseInt() function:

yourNumber = parseInt(hexString, 16);

The 16 as the second argument specifies the base of the hexadecimal number system.

To illustrate, let's convert the decimal number 255 to hexadecimal:

hexString = 255.toString(16); // Result: "ff"

To retrieve the original decimal value from the hexadecimal string:

decimalNumber = parseInt("ff", 16); // Result: 255
